Abstract
Description
Technical Field
[0001] This utility model relates to the field of patient turning aids; more specifically, it relates to a patient turning aid. Background Technology
[0002] Dialysis and interventional care are indispensable components of modern medicine. Dialysis, primarily used to replace detoxification in patients with insufficient kidney function, includes two forms: hemodialysis and peritoneal dialysis, maintaining life by removing waste products and excess water from the body. Interventional care involves treatments performed through minimally invasive surgery and image-guided techniques, such as catheter placement, biopsy, and stent implantation, aiming to provide patients with precise medical intervention and monitoring. The combination of these two approaches can significantly improve the quality of life and clinical outcomes for patients with serious illnesses.
[0003] Currently, existing patient turning aids have several limitations. Most require patients to rely on their own strength to turn over, and since patients vary in strength, some weaker patients find it difficult to turn over, making the devices inconvenient to use and reducing their applicability. Furthermore, the fixed handrails of some existing devices make it difficult for medical staff to care for patients in bed, further reducing their practicality. Therefore, there is an urgent need for a patient turning aid to solve these problems. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a patient turning aid to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: a patient turning assist device, comprising:
[0006] The base has a flipping structure on its upper surface and a handrail structure on one end of its surface.
[0007] The turning structure includes a connecting block, which is fixedly connected to the middle position of the upper outer surface of the base, and there are two sets of connecting blocks.
[0008] The handrail structure includes a fixing plate, which is fixedly connected to the outer surface of one end of the base.
[0009] Preferably, the turning structure further includes a support plate, and the support plate is provided in two sets. The two sets of support plates are respectively hinged to both sides of the connecting block. The outer surfaces of both sides of the base are provided with grooves, and the grooves are provided with first hinge blocks. The upper outer surface of the first hinge block is fixedly connected to the lower outer surface of the support plate. The lower end of the first hinge block is hinged to a connecting plate, and the lower end of the connecting plate is hinged to a second hinge block. The two ends of the second hinge block are fixedly connected to sliding blocks. The bottom of the groove is provided with first moving slots on both sides. The bottom surfaces of the two sets of grooves are installed with a first motor on one side close to each other, and the output end of the first motor is fixedly connected to a first lead screw. This design allows the support plate to be hinged and rotated on the upper surface of the base.
[0010] Preferably, the length of the first hinge block is adapted to the length of the groove, the external dimensions of the sliding blocks fixedly connected to both ends of the second hinge block are adapted to the internal dimensions of the first moving groove, and the outer surface of the middle position of the second hinge block is sleeved on the outer surface of the first lead screw. This design makes the second hinge block more stable when moving inside the groove, and the second hinge block can be moved by rotating the first lead screw.
[0011] Preferably, the handrail structure further includes a second movable groove, which is located inside the fixed plate. A second motor is installed at the upper end of the middle position inside the second movable groove, and the output end of the second motor is fixedly connected to a second lead screw. Support side plates are fixedly connected to the outer surfaces of both ends of one side of the fixed plate, and a third movable groove is provided inside the support side plates. Guardrails are inserted inside the third movable groove. One end of each of the two sets of guardrails is fixedly connected to a connecting strip, and the middle position of the connecting strip is sleeved on the outer surface of the second lead screw. Support strips are inserted inside the outer surfaces of the two sets of support side plates that are away from each other, and a threaded rod is connected to the bearing at the middle position of the outer surface of one side of the support strip. This design allows the two sets of guardrails to move synchronously inside the two sets of third movable grooves through the connecting strips.
[0012] Preferably, the internal dimensions of the third moving groove are adapted to the external dimensions of the guardrail, and the external dimensions of the connecting strip are adapted to the internal dimensions of the second moving groove. This design makes the guardrail more stable when moving inside the third moving groove, and also makes the connecting strip more stable when moving inside the second moving groove.
[0013] Preferably, the two sets of support side plates have storage grooves inside the surfaces of the two sets of support side plates that are far apart from each other, and the internal dimensions of the storage grooves are adapted to the external dimensions of the support bars. The position of the support bars corresponds to the position of the guardrail. The outer surface of one end of the threaded rod is threaded to the inside of the outer surface of one side of the support side plate. This design allows the support bars to move inside the storage grooves and allows the upper surface of the support bars to fit against the bottom surface of the guardrail.
[0014] The technical effects and advantages of this utility model are as follows: By starting the first motor, the first motor drives the first lead screw to rotate. When the first lead screw rotates, it drives the second hinge block to move. At the same time, when the second hinge block moves, it drives the connecting plate to rotate synchronously with the first hinge block. Then, the first hinge block can drive the support plate to rotate. Thus, by starting the first motor, the support plate can be rotated by hinge, so that the patient can turn over without relying on his own strength, which improves the applicability of the equipment to a certain extent.
[0015] By rotating the threaded rod, the support bar moves into the storage slot. The second motor is then activated, causing the second lead screw to rotate and drive the connecting bar to move downwards inside the second moving slot. Simultaneously, the connecting bar drives the guardrail to move downwards inside the third moving slot, thus storing the guardrail inside the third moving slot. This facilitates medical staff in providing care to patients lying on the upper surface of the support plate, improving the practicality of the equipment to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The patient turning aid involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Example 1
[0024] like Figure 1 and Figure 2 As shown, this embodiment proposes a patient turning assist device, including:
[0025] The base 1 has a flipping structure 2 on its upper surface and a handrail structure 3 on one end of its surface.
[0026] The turning structure 2 includes a connecting block 21, which is fixedly connected to the middle position of the upper outer surface of the base 1, and the connecting block 21 is provided in two sets.
[0027] The turning structure 2 also includes a support plate 22, and there are two sets of support plates 22. The two sets of support plates 22 are respectively hinged to both sides of the connecting block 21. The outer surface of both sides of the base 1 has a groove 23 inside, and a first hinge block 24 is provided inside the groove 23. The upper outer surface of the first hinge block 24 is fixedly connected to the lower outer surface of the support plate 22. The lower end of the first hinge block 24 is hingedly connected to a connecting plate 25, and the lower end of the connecting plate 25 is hingedly connected to a second hinge block 26. The two ends of the second hinge block 26 are fixed. The groove 23 is connected to a sliding block. The bottom of the groove 23 has two first moving grooves 27 on both sides. The bottom surfaces of the two sets of grooves 23 are close to each other and the first motor 28 is installed inside. The output end of the first motor 28 is fixedly connected to the first lead screw 29. The length of the first hinge block 24 is adapted to the length of the groove 23. The two ends of the second hinge block 26 are fixedly connected to the external dimensions of the sliding block, which are adapted to the internal dimensions of the first moving groove 27. The outer surface of the second hinge block 26 at the middle position is sleeved on the outer surface of the first lead screw 29.
[0028] In this embodiment, the design starts the first motor 28 to rotate the first lead screw 29. At this time, the second hinge block 26 moves on the outer surface of the first lead screw 29. The sliding blocks at both ends of the second hinge block 26 move synchronously inside the first moving groove 27, so that the second hinge block 26 can move more stably.
[0029] Example 2
[0030] like Figures 3-5 As shown, based on the same concept as the above embodiments, this embodiment also proposes:
[0031] The handrail structure 3 includes a fixing plate 31, and the fixing plate 31 is fixedly connected to the outer surface of one end of the base 1;
[0032] The handrail structure 3 also includes a second movable groove 32, which is located inside the fixed plate 31. A second motor 33 is installed at the upper end of the middle position inside the second movable groove 32, and the output end of the second motor 33 is fixedly connected to a second lead screw 34. Support side plates 35 are fixedly connected to the outer surfaces of both ends of one side of the fixed plate 31, and a third movable groove 36 is provided inside the support side plate 35. Guardrails 37 are inserted inside the third movable groove 36. A connecting strip 38 is fixedly connected to one end of each of the two sets of guardrails 37, and the middle position of the connecting strip 38 is sleeved on the outer surface of the second lead screw 34. The two sets of support side plates 35 are mutually... A support bar 39 is inserted inside the outer surface away from one side, and a threaded rod 310 is connected to the bearing at the middle position of the outer surface of the support bar 39. The internal dimensions of the third moving groove 36 are adapted to the external dimensions of the guardrail 37. The external dimensions of the connecting bar 38 are adapted to the internal dimensions of the second moving groove 32. The two sets of support side plates 35 have storage grooves inside the outer surface away from each other, and the internal dimensions of the storage grooves are adapted to the external dimensions of the support bar 39. The position of the support bar 39 corresponds to the position of the guardrail 37. The outer surface of one end of the threaded rod 310 is threaded to the inside of the outer surface of one side of the support side plate 35.
[0033] In this embodiment, the design makes the guardrail 37 more stable when moving inside the third moving groove 36, and the connecting strip 38 more stable when moving inside the second moving groove 32. Furthermore, through the design of the storage groove, the support strip 39 can move inside the third moving groove 36 and inside the storage groove, and the position of the support strip 39 corresponds to the position of the guardrail 37. After the support strip 39 moves out of the storage groove, the upper surface of the support strip 39 fits against the bottom of the guardrail 37, thereby supporting the position of the guardrail 37.
[0034] Working principle: When the device is in use, the first motor 28 is started first, which drives the first lead screw 29 to rotate. When the first lead screw 29 rotates, it drives the second hinge block 26 to move inside the groove 23. When the second hinge block 26 moves, it can drive the connecting plate 25 to rotate hingedly. Then, the hinged rotation of the connecting plate 25 drives the first hinge block 24 to move, so that the support plate 22 fixedly connected to the upper surface of the first hinge block 24 can rotate hingedly through the connecting block 21. This starts the first motor 28, and with the cooperation of the support plate 22, the patient can turn over by himself.
[0035] When a patient needs a handrail, the second motor 33 is activated, causing the second lead screw 34 to rotate and move the connecting bar 38 inside the second moving groove 32. Simultaneously, the connecting bar 38 moves the guardrail 37 inside the third moving groove 36. When the guardrail 37 reaches the top of the third moving groove 36, the threaded rod 310 is rotated to disengage the support bar 39 from the storage groove, causing the upper surface of the support bar 39 to fit against the bottom surface of the guardrail 37. This provides support for the guardrail 37. When medical staff need to care for the patient, the above operation can be reversed to store the guardrail 37, thus facilitating patient care. This is the complete working principle of this utility model.
[0036] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
